Nothing has changed on my network, with my setup, with anything in our environment. I haven't touched the SW server and the only other app on my SW server is WUS. I have both pieces of software setup to work at completely different times to prevent any conflicts.When SW is scanning, it's putting previously scanned devices as Unknowns listed only by the serial number.

I thought it was possible that the machine(s) were turned off while the subnet was being scanned. I deleted the Unknown, as the real device was still listed in my inventory. I verified the device was online, with the same IP, and rescanned it manually by selecting the device in my inventory screen and selecting the scan now button. It still came up as a new unknown listed only by serial number.

To make things more interesting, I rescanned one of my unknowns and it came back with a new unknown with a different serial number?! Most of my devices have static IP addresses, and the few that use DHCP, have a reserved address so it's not an issue where devices are changing IP's. I've check my DNS and it's fine. There's no unexpected pink entries in SW.

I am running version 2.0.17490 of SW and this has just started happening. Any ideas?

I mean the Windows Update themselves. Unfortunately, we have not been able to "prove" anything but we have seen several users have problems after performing a Windows Update. I'm glad the latest scan yielded no Unknowns. Keep me updated.
